OCALA, Fla. — New health requirements mean children may need an additional polio vaccination before they can enter kindergarten. Students entering seventh grade need the tetanus-diphtheria-pertussis, or Tdap vaccine. Students in higher grades may also need the Tdap vaccine.

Some other vaccination requirements include:

Kindergarten through the fifth grade: two doses of the varicella vaccine.

Grades 5 to 11: one dose of the varicella vaccine.

Students entering a Florida school for the first time should have two doses of the measles, mumps and rubella vaccines.

The Marion County Health Department immunization clinic is located in Ocala at 1801 S.E. 32nd Ave. Directions are available online at doh.state.fl.us. The clinic is open weekdays from 8 a.m. to 4:15 p.m. Immunizations are free for people ages 18 and younger. No appointment is needed at the department’s Ocala office.

State health officials strongly encourage parents to get their children immunized early and beat the rush before schools reopen.
